He is perhaps best known for his play during the 1991 Stanley Cup playoffs in place of injured Penguins' starting goaltender Tom Barrasso. In Game 6 of the opening round against the New Jersey Devils, Pietrangelo helped the Penguins stave off elimination with one of the most significant stops in Stanley Cup history, a glove save against Peter Stastny, who was shooting at a mostly-open net at point-blank range. The play, which would become known simply as "The Save," helped the Penguins win the game and the series. The Penguins, with a healthy Barrasso, would eventually win their first Stanley Cup.[1]
